Abstract
A new method of treatment of migraine, tension-type headaches, post-traumatic headache, atypical facial pain as well as cervical pain and muscle spasm is presented, comprising the application of bursts of low power laser light to the area of intra-oral tenderness associated with the above conditions. The zone of tenderness is in the area of the plexus formed by the posterior and middle superior alveolar branches of the ipsilateral maxillary nerve. The intra-oral tenderness associated with migraine, tension-type headaches, post-traumatic headache, atypical facial pain, cervical pain and muscle spasm disappears almost immediately, returning in approximately 3 hours to a few days, With repeated applications, a marked decrease or elimination of the intra-oral tenderness and similar elimination of migraine, tension-type headaches, post-traumatic headache, atypical facial pain, cervical and muscle spasm frequency and intensity was observed. The brief application of bursts of low power laser light (non-cutting 5-60 mW) from a low power Helium-Neon, Gallium Arsenide or Gallium Aluminum Arsenide laser, having a maximum output of 60 mW ,typically utilizing an application time of 2-15 minutes…
